NASA Nationals at Miller really hurt their growth. Too far from everywhere. If you want the runoffs on the west coast then do them there. Do it where you can get a date.

Otherwise plan to travel.

Here's the bottom line. There are few tracks in the country that can accomidate the number of rigs and race cars that the runoffs requires. I doubt WG can. ViR is borderline. Daytona can. MidOhio perhaps.

Its also true that dates are very hard to get. The better tracks are full now. They are not going to upset their regular customer schedule and jump thru the hoops required to host an event like the runoffs for just one year. They want an extended deal.
If you want to rotate it, it needs to be part of the contracted plan. 3 years here. Then 3 years at venue #2 and then 3 year back and venue #1. All in the same contract.
